Computer Vision for Microscopes

The EU MiCRoN project has finished and the Computer Vision Software was delivered. To solve the vision task in a microscopic environment, Geometric Hashing was used as recognition algorithm and the Bounded Hough Transform for tracking in subsequent images.

The software is available under the LGPL here.

My private robot project still hasn't advanced lately.

However here is another demonstration of the work, which I'm doing at University.

My private robot-project hasn't advanced lately.
However there are news in context with the MiCRoN-project.
M. Boissenin (a PhD student) and me have achieved results, which may be a small breakthrough in the specialised field of computer-vision for microscopes.

For more information, see the results-page.

Unfortunately there are conflicting requirements on the kernel-version (by ndiswrapper for running Wireless-card and by the RTAI realtime operating system). I'll leave this problem for later.

I bought the PCAN interface, which is a buffered interface between a CAN-bus and a USB-port. Peak-systems are also offering an obfuscated-source driver (see driver-page).

The next step is a difficult one for me: I'll have to connect microcontrollers to a CAN-bus (and to sensors and actors of course).

So far I tried an Infineon-C167, which was at hand. I gave up, because there is no properly documented gcc-backend.

I'll have to try Atmel AVR next. It seems to have a strong developer-base. So I feel safer to go in this direction.

I've so far set up a Mini-ITX computer, which is (appart from an external power-supply at the moment) already fully self-sufficient. One can communicate with the Mini-ITX PC by wireless network. Here's the detailed documentation: documentation

Using CANBus and micro-controllers in the future, it should be possible to build a robot with Onboard-PC for less than 1000 Euros!

CANBus is used in professional applications (cars, industrial robots). F.e. see Kurt2 project.
